        <p>大年初五，大家都在迎财神</p>
<p>今天给大家介绍一位看得见摸得着的财神 —— 比特币</p>
<a id="more"></a>
<h2 id="迅猛的比特币">迅猛的比特币</h2>
<p>比特币从09年问世以来，从最初的毫无价值(一度还不如一个QQ币)，到现在的一个可以买辆特斯拉(写这段文字的时候价格是32万人民币)</p>
<p>我去年（2020年）8月份入场时，大概8万元，当时我们小区一个车位大概8万，当时还纠结了一阵，现在车位还是那个价</p>
<p>再回到几年前，我在火币上两千元左右买了一个比特币，拿了两三个月，各种风言四起，赶紧买掉了，当时还庆幸赚了两千块，现在后悔的都不愿意提起这事儿了</p>
<p>还好，现在上了BOX的高速快车了，买不起一个股票，可以买基金嘛</p>
<h2 id="为啥呢？">为啥呢？</h2>
<p>为啥这个当初为了验证区块链技术可行性的技术玩具——比特币，他的的价值如此强悍呢？</p>
<h3 id="足够的安全">足够的安全</h3>
<p>️首先是因为比特币足够的安全</p>
<p>它的安全不是谁来保证的，而是</p>
<blockquote>
<p>由一个巨大的分布式网络，以及运行在其上的算法保证的</p>
</blockquote>
<p>这样说可能有些不好理解，打个比方</p>
<p>就像一个由好多相互不认识的人管理一个账本，每天(比特币账本为每10钟)其中的大多数人对一天之内发生的账目进行统计确认，并签名</p>
<p>因为谁也不认识谁，也就不会偏袒谁，如果谁想给自己多记点，那就需要让大多数记账员同意他这么记，大多数是多少呢，至少是51%的人数</p>
<p>这意味着记账的人数越多，让51%的人同意自己作弊的可能性越小</p>
<p>你可能会说可能性小不代表不可能呀，没错</p>
<p>但是如果你能控制区块链网络里 51% 的计算机(数以亿计)，干点啥不行，何必在乎修改比特币账本这点蝇头小利呢(还不明白的话请自行补下博弈论)</p>
<p>而且随着比特币越来越普及，影响力越来越大，参与计算的设备(不止是计算机)越来越多</p>
<p>赢得51%的难度将会指数级提升(指数级可以理解成细胞分裂，1个变两个，两个变4个，4个变8个…，这样的速度), 几近于不可能</p>
<h3 id="链接的资源更广">链接的资源更广</h3>
<p>️然后是使用的人越来越多价值就越高</p>
<p>为啥用的人越多越有价值呢？打个比方</p>
<p>我们的圈子里来了个新人，开始大家都不认识他，谁也不理他，慢慢地，他和圈里的某些人发生了交互，渐渐地更多的人和他有了交道，于是这个原本的新人融入了我们的圈子</p>
<p>如果他是一个正直友善，公平理性的人，他影响力就会更大，会逐渐成为圈子的中心</p>
<p>那么这时让他离开这个圈子，从此消失，我不用说，你都会急，因为他已经是我们的一部分，说不定还欠你的钱呢</p>
<p>这就是比特币作为一个新人逐渐融入世界经济这个圈子的过程</p>
<p>前脚特斯拉宣布入资比特币，后脚苹果宣布入资比特币，越来越多的实体资源和比特币产生关联，那么他的价值就会越来越高</p>
<p>这也是我之前说的如果有人对你说: &quot;比特币已经错过了，不要再错过XXX&quot;是骗子的原因</p>
<p>因为即使是一个品学兼优的人，融入圈子也需要很长时间，更何况知人知面不知心呢</p>
<h3 id="避风港">避风港</h3>
<p>️最后，比特币的价格为什么会飞涨呢？</p>
<blockquote>
<p>注意: 是价格不是价值，不要看见价格高，就觉得价值高，反之亦然市场上很多东西价值和价格是不相符的，这就是为什么靠谱的投资经理会告诉你要看市盈率的原因</p>
</blockquote>
<p>如果你大致明白前面两点，那么这一点就很容易理解了</p>
<blockquote>
<p><strong>比特币是资金的避风港</strong></p>
</blockquote>
<p>因为他足够的安全，而且不能增发(<code>只有2500万个，预计140年后会全部拿出，这是由比特币算法设定的，改变不了</code>)，也就是不会有通货</p>
<p>当去年特朗普政府为了保证经济，大肆增发美元时(印钞比例超过以往美元印钞总量的70%，预计新政府还会加印)</p>
<p>多出来的钱并不平均分配到每个人手里，而是聚集在有资源有能力的少数人手里</p>
<p>又，增发钞票意味着美元贬值，怎么办，比特币成为香饽饽，大量的资金涌入，比特币的价格应声而起，成了名副其实的避风港</p>
<p>于是形成了正向的飞轮效应:</p>
<blockquote>
<p>越安全链接的资源就越广，链接的资源越广价值就越高，价值越高参与的设备就越多参与的设备越多，就越安全</p>
</blockquote>
<h2 id="没有坏问题">没有坏问题</h2>
<p>到这里，你一定会问: 既然这么好了，为啥不直接代替货币呢？</p>
<p>为啥听说很多人因为电脑坏，硬盘丢等等，丢失了很多比特币呢？</p>
<p>不瞒你说，确实是这样的，原因是什么呢？</p>
<ol>
<li>
<p>为什么不能作为日常使用？由于比特币的算法和机制，致使记账周期为10分钟，即使以太坊将时间缩短到一分钟，用惯微信支付宝的我们还是接受不了。另外，作为市场上的新人，不稳定性会长存，波动巨大，不适应做日常货币</p>
</li>
<li>
<p>为啥会丢呢？确实会丢失，不过不是因为比特币的漏洞造成的，而是因为使用比特币钱包需要记住巨长无比的私钥(一串几千个无规律的字符编码)，靠人脑几乎是记不住的，于是只能存起来，但容易丢，不过办法总比问题多，数字货币易用性解决方案 Mixin 的出现解决了这个问题，后续文章会着重介绍 Mixin</p>
</li>
</ol>
<h2 id="结尾">结尾</h2>
<p>好了，今天就聊到这里，为了让大家更容易的理解，对比特币的各种比喻可能存在不够严谨的地方，请多多包涵，敬请指正</p>
<p>也欢迎您随时交流与咨询</p>
<p>祝 顺利迎财神，好运连连，财源滚滚</p>
